DETAILED DESCRIPTION

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” etc., is used with reference to the orientation of the Figure (s) being described. The components of the present invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.

Please refer to FIG. 1 to FIG. 4. FIG. 1 is a diagram of a rotary laundry device 1 according to a first embodiment of the present invention. FIG. 2 is an installation diagram of the rotary laundry device 1 according to the first embodiment of the present invention. FIG. 3 is a diagram of a supporting component 12 of the rotary laundry device 1 according to the first embodiment of the present invention. FIG. 4 is a partial diagram of the rotary laundry device 1 according to the first embodiment of the present invention. As shown in FIG. 1 to FIG. 4, the rotary laundry device 1 includes a driving main body 11, the supporting component 12, a connecting component 13 and a cleaning component 14. The driving main body 11 is located inside an inner tub 21 of a laundry machine 2. A plurality of protruding portions 111 protrude from the driving main body 11. A blocking surface is formed on each protruding portion 111 for providing resistance for water or clothing inside the inner tub 21. The supporting component 12 is detachably installed on the inner tub 21 of the laundry machine 2. Three mounting lugs 123 protrude from the supporting component 12 and disposed in a circular arrangement. Preferably, in this embodiment, an included angle between the two adjacent mounting lugs 123 can be 120 degrees, i.e., the three mounting lugs 123 can be spaced apart at equal intervals. However, the present invention is not limited to this embodiment. Three mounting holes 211 are formed on the inner tub 21 of the laundry machine 2 and located at positions corresponding to the three mounting lugs 123. The three mounting lugs 123 can pass through and engage with the three mounting holes 211 on the inner tub 21 of the laundry machine 2. The supporting component 12 is installed on the inner tub 21 of the laundry machine 2 by engagement of the three mounting lugs 123 and the three mounting holes 211.

The connecting component 13 rotatably passes through the supporting component 12. A first end 131 of the connecting component 13 is connected to the driving main body 11. The cleaning component 14 is connected to a second end 132 of the connecting component 13 opposite to the first end 131 of the connecting component 13 and substantially perpendicular to the connecting component 13. The cleaning component 14 is located between the inner tub 21 and an outer tub 22 of the laundry machine 2. Preferably, in this embodiment, the cleaning component 14 can be a brush or a soft spatula. However, the present invention is not limited thereto. In such a way, when the blocking surface is forced by the water or the washed clothing, the driving main body 11 can be driven to drive the connecting component 13 to rotate together with the driving main body 11 relative to the inner tub 21 of the laundry machine 2 and further can increase turbulence of flow of the water by the blocking surface for improving cleanliness of the washed clothing. Furthermore, when the driving main body 11 is lashed by the water or the clothing to drive the connecting component 13 to rotate together with the driving main body 11 relative to the inner tub 21 of the laundry machine 2, the connecting component 13 can drive the cleaning component 4 to rotate relative to the inner tub 21 and the outer tub 22 of the laundry machine 2 to clean the inner tub 21 and the outer tub 22.

When beginning to operate the laundry machine 2, the inner tub 21 can be filled with water, and the driving main body 11 can be sunk into the water. The water inside the inner tub 21 can be driven by the laundry machine 2 to form a whirly flow. Since the blocking surface is formed on each protruding portion 111 of the driving main body 11, the water lashes the blocking surface to drive the driving main body 11 to rotate when the water flows through the driving main body 11. Besides, when the clothing inside the inner tub 21 passes by the driving main body 11, the clothing also lashes the blocking surface to drive the driving main body 11 to rotate. Furthermore, the driving main body 11 can further swipe the water by the blocking surface to increase turbulence of the flow of the water when the driving main body 11 rotates. By the turbulence, it can increase the friction between the clothing and the water, so that the cleanliness of the washed clothing is improved. In other words, in the present invention, since the driving main body 11 can be driven by the water inside the inner tub 21 to rotate, the rotation of the driving main body 11 can change a flow field of the water and increase the turbulence of the flow of the water accordingly, which causes a coupling effect. Therefore, the flow field of the water inside the inner tub 21 gradually changes with time and can be regarded as an unstable flow field. Since the unstable flow field has the stronger turbulence, which facilitates transmission of momentum of the water, the present invention can improve the cleanliness of the washed clothing.

It should be noticed that the structure of the rotary laundry device is not limited to this embodiment. For example, in another embodiment, the rotary laundry device can include the driving main body, the supporting component and the connecting component only, i.e., the cleaning component can be omitted. Furthermore, the number and the arrangement of the mounting lug are not limited to this embodiment. For example, in another embodiment, there can be only two mounting lugs protruding from the supporting component and arranged diagonally and oppositely, i.e., an included angle between the two mounting lugs is 180 degrees.

Specifically, the supporting component 12 includes a first portion 121 and a second portion 122 connected to the first portion 121 and adjacent to the cleaning component 14. A distance between an outer periphery P1 of the first portion 121 and a rotating axis S of the connecting component 13 gradually increases along a first direction R1 parallel to the rotating axis S of the connecting component 13. A distance between an outer periphery P2 of the second portion 122 and the rotating axis S of the connecting component 13 gradually decreases along the first direction R1 parallel to the rotating axis S of the connecting component 13. The three mounting lugs 123 are located at a connection of the first portion 121 and the second portion 122 of the supporting component 12 and extend away from the rotating axis S of the connecting component 13 for engaging with the three mounting holes 211. Furthermore, the supporting component 12 further includes two restraining structures 124. The two restraining structures 124 respectively extend from the first portion 121 and the second portion 122 toward the driving main body 11 and the cleaning component 14 for respectively abutting against the driving main body 11 and the cleaning component 14 to restrain an axial displacement of the connecting component 13 relative to the supporting component 12 and parallel to the rotating axis S of the connecting component 13. Therefore, the axial displacement of the connecting component 13 along the first direction R1 or a second direction R2 opposite to the first direction R1 can be restrained by the two restraining structures 124 for preventing disengagement of the connecting component 13 from the supporting component 12 along the first direction R1 or the second direction R2 even if the connecting component 13 is forced by an external force along the first direction R1 or the second direction R2. Besides, preferably, in this embodiment, the supporting component can be a symmetrical gyro-shaped structure. However, the present invention is not limited to thereto. It depends on practical demands. For example, in another embodiment, the supporting component can only include the first portion and the restraining structure extending from the first portion toward the driving main body.

In addition, in this embodiment, an installing notch 212 is formed on the inner tub 21. The three mounting holes 211 are formed on a wall 2121 of the installing notch 212 of the inner tub 21 and disposed in a circular arrangement. When the rotary laundry device 1 is installed on the inner tub 21, the rotary laundry device 1 can be preferably partially accommodated inside the installing notch 212, i.e., only the driving main body 11 of the rotary laundry device 1 is partially exposed out of the installing notch 212, for preventing the clothing from wrapping the driving main body 11, the supporting component 12 or the connecting component 13 due to excessive protrusion of the rotary laundry device 1. However, in another embodiment, the driving main body can be configured to be fully exposed out of the installing notch. It depends on practical demands.

Furthermore, in order to bring convenience in installation and detachment of the rotary laundry device 1, the three mounting lugs 123 can be preferably be made of resilient material. When it is desired to install or detach the supporting component 12, it only has to press the mounting lugs 123 to resiliently deform to engage with or disengage from the mounting holes 211 for achieving installation or detachment of the supporting component 12. Besides, please refer to FIG. 3 to FIG. 5. FIG. 5 is a diagram of a detaching assembly 15 according to the first embodiment of the present invention. As shown in FIG. 3 to FIG. 5, the rotary laundry device 1 further includes the detaching assembly 15. The detaching assembly 15 includes an abutting component 151 and a prying component 152. The abutting component 151 includes an abutting operating portion 1511 and three abutting portions 1512 connected to the abutting operating portion 1511 and for abutting against the three mounting lugs 123. The prying component 152 includes a prying operating portion 1521 and a prying portion 1522 connected to the prying operating portion 1521 and for abutting against the driving main body 11. When it is desired to detach the rotary laundry device 1 from the inner tub 21, the abutting operating portion 1511 can be operated to insert the abutting portions 1512 into the installing notch 212 to press the mounting lugs 123 to resiliently deform. Afterwards, the prying operating portion 1521 can be operated to drive the prying portion 1522 to abut against a side of the driving main body 11 adjacent to the supporting component 12 to pry the driving main body 11 along the second direction R2, so that the supporting component 12 can be detached easily. Preferably, in this embodiment, the prying portion 1522 can be a U-shaped structure, and the prying operating portion 1521 can be connected to a middle portion of the U-shaped structure. Furthermore, preferably, the abutting operating portion 1511 can be a regular triangular structure. However, the present invention is not limited to this embodiment. It depends on practical demands. For example, in another embodiment, the abutting operating portion can be a polygon-shaped structure or a circular structure. Besides, the number and the arrangement of the abutting portion are not limited to this embodiment. It depends on practical demands, e.g., it can depend on the number and the arrangement of the mounting lug.

In order to enhance using convenience of the abutting component 151, the three abutting portions 1512 are movably connected to the regular triangular structure, i.e., the abutting operating portion 1511. The three abutting portions 1512 can be moved to three peaks of the regular triangular structure to correspond to the three mounting lugs 123. The regular triangular structure includes a first operating member 1511A and a second operating member 1511B at each side. The first operating member 1511A is connected to the second operating member 1511B and bendable relative to the second operating member 1511B. Each abutting portion 1512 includes a first abutting member 1512A, a second abutting member 1512B and a third abutting member 1512C. Two ends of the first abutting member 1512A are respectively connected to the abutting operating portion 1511 and the second abutting member 1512B. The second abutting member 1512B is further connected to the third abutting member 1512C. A first included angle A1 is formed between the first abutting member 1512A and the abutting operating portion 1511. The first abutting member 1512A is bendable relative to the abutting operating portion 1511 to adjust the first included angle A1. A second included angle A2 is formed between the first abutting member 1512A and the second abutting member 1512B. The second abutting member 1512B is bendable relative to the first abutting member 1512A to adjust the second included angle A2. A third included angle A3 is formed between the second abutting member 1512B and the third abutting member 1512C. The third abutting member 1512C is bendable relative to the second abutting member 1512B to adjust the third included angle A3. In such a way, the user can bend the first abutting member 1512A relative to the abutting operating portion 1511, bend the second abutting member 1512B relative to the first abutting member 1512A, and bend the third abutting member 1512C relative to the second abutting member 1512B to fold or unfold the abutting component 151. The folded abutting component 151 has compact occupied space, which facilitates storage or portability.

Moreover, as shown in FIG. 1 and FIG. 2, in this embodiment, the rotary laundry device 1 can further include a resilient component 16 abutting between the supporting component 12 and the inner tub 21. Preferably, the resilient component 16 can be a compression spring that is forced to resiliently be compressed when the supporting component 12 is installed on the inner tub 21. When the mounting lugs 123 are forced to resiliently deform, the resiliently compressed resilient component 16 can drive the supporting component 12 to disengage the mounting lugs 123 from the mounting holes 211 along the second direction R2 by a resilient recovering force, which makes the detachment of the supporting component 12 more convenient and labor-saving.

Two restraining structures 124′ are respectively formed on two ends of the hollow pipe 122′ for respectively abutting against the driving main body 11′ and the cleaning component 14′. Two mounting lugs 123′ protrude from the supporting plate 121′ and arranged oppositely. Understandably, in this embodiment, there can be two mounting holes formed on the inner tub. A through hole 125′ is formed on the supporting plate 121′. The hollow pipe 122′ passes through the through hole 125′. The connecting component 13′ passes through the hollow pipe 122′. A slit 126′ is further formed on the supporting plate 121′. The slit 126′ is communicated with the through hole 125′ and extends to an outer periphery P3 of the supporting plate 121′ through one of the two mounting lugs 123′. By the configuration of the slit 126′, the user can operate the supporting plate 121′ to allow disengagement of the hollow pipe 122′ through the through the slit 126′, which facilitates detachment of the hollow pipe 122′ and/or the connecting component 13′.

Furthermore, a first end 131′ of the connecting component 13′ is detachably connected to the driving main body 11′. Specifically, an accommodating chamber 112′ and an opening 113′ communicated with the accommodating chamber 112′ are formed on the driving main body 11′. The first end 131′ of the connecting component 13′ for connecting the driving main body 11′ can be a T-shaped structure. The T-shaped structure includes two lateral portions 1311′ respectively extending toward two opposite directions. A sum of lengths of the two lateral portions 1311′ is greater than a length of the opening 113′, and the accommodating chamber 112′ is for accommodating the two lateral portions 1311′. The user can move the two lateral portions 1311′ to pass through the opening 113′ into the accommodating chamber 112′ by movement of the T-shaped structure relative to the driving main body 11′ for achieving connection of the first end 131′ of the connecting component 13′ and the driving main body 11′. On the other hand, the user also can move the two lateral portions 1311′ out of the accommodating chamber 112′ via the opening 113′ for achieving disconnection of the first end 131′ of the connecting component 13′ and the driving main body 11′.

By the configuration of the slit 126″, the user can operate the supporting plate 121″ to allow disengagement of the connecting component 13″ through the slit 126′, which facilitates detachment of the connecting component 13″.

Besides, the connecting component 13″ includes a shaft body 133″ and two restraining portions 134″. The shaft body 133″ rotatably passes through the supporting plate 121″. Two ends of the shaft body 133″ are respectively connected to the driving main body 11″ and the cleaning component 14″. The two restraining portions 134″ protrude from the shaft body 133″ and located adjacent to two opposite sides of the supporting plate 121″. The two restraining portions 134″ are for abutting against the supporting plate 121″ to restrain an axial displacement of the connecting component 13″ relative to the supporting plate 121″ and parallel to a rotating axis of the connecting component 13″. Preferably, in this embodiment, the restraining portion 134″ can be a protruding ring-shaped structure whose outer diameter can be greater than an inner diameter of the through hole 125″.
